Power LED, also known as high-power LED, is a type of light-emitting diode that emits a high intensity of light. With the continuous development of technology and the increasing demand for energy-saving and environmental protection, power LED has become an indispensable part of the lighting industry. This article will introduce the industry of power LED, including its definition, development history, market status, application fields, and future prospects.

Definition and Characteristics of Power LED

Power LED refers to the LED with a luminous flux greater than 100 lumens and a forward current greater than 350mA. Compared with traditional lighting, power LED has the following characteristics:

• High luminous efficiency: The luminous efficiency of power LED can reach up to 150lm/W, which is much higher than that of traditional lighting.
• Long life span: The life span of power LED can reach 50,000 hours or even longer, which is 10 times longer than that of traditional lighting.
• Low power consumption: The power consumption of power LED is only 1/10 of traditional lighting, which is very energy-saving.
• Small size and light weight: Power LED has a small size and light weight, which is very convenient for installation and maintenance.

Development History of Power LED

The development of power LED can be traced back to the 1960s. At that time, the luminous efficiency of LED was very low, and it was only used as a signal light. With the continuous development of semiconductor technology, the luminous efficiency of LED has been improved, and the application field has been expanded. In the 1990s, the development of power LED entered a fast track. With the continuous optimization of the structure and materials of power LED, its performance has been greatly improved, and its application field has been further expanded.
